AngularJS - Can I use data binding value depending on ternary operator

Question

I have an ng-repeat li elements and I want to set a specific value for that li depending on whether a function returns true or false and I don't want to do it in the controller because I have dependency issues where it makes it Minimize or Maximize for ALL li elements but I want it to be for each individual li element. I tried using several things including the following without any luck. I am not sure what I am doing wrong but I would appreciate any input or any other way of doing this.

object1 is from an ng-repeat that includes this li element.

<li><a tabindex="-1" ng-click="setHidden(object1)">{isItHidden(object1) ? 'Minimize' : 'Maximize'}</a></li>

SOLUTION (thanks to jdp)

<li><a tabindex="-1" ng-click="setHidden(object1)">{{isItHidden(object1)}}</a></li> $scope.isItHidden = function(object){ return object.hidden ? 'Maximize' : 'Minimize'; }

kindly share complete html and js file object1 is not visible in the code — Ajay Singh Beniwal

You can't do logic like that in a view. Why couldn't you have $scope.isItHidden(obj) return either 'Minimize' or 'Maximize? If you're passing in the specific object as a function parameter there shouldn't be any interference. Could you share your controller and some sample data? — jdp

With the release of angular 1.2, you can now use the more intuitive ternary operator inside ng-bind

<a ng-bind="object1.hidden ? 'Maximize' : 'Minimize'"></a>

or inside brackets

<a>{{ object1.hidden ? 'Maximize' : 'Minimize' }}</a>

You can do this

{{ object1.hidden && 'Minimize' || 'Maximize' }}

In angular 1.2 a real ternary operator will be added.

Now when 1.2 is released, the ternary operator is described here stackoverflow.com/questions/12008580/…
